We wrote a ritual for Lughnassadh but plans fell through and we were unable to perform it. We have posted the text on our Lammas page in case anyone else wants to use it. The theme is drought and harvest.

So as a fallback we shifted to an esbat, because the moon is full tonight, and we kept the drought theme. You can see that on our main Esbats page, since it follows our "ordinary" and seemed like a useful example to share.
